A third UCLA player has been ruled out due to concussions this week as running back Bolu Olorunfunmi was declared out by the medical staff Tuesday afternoon, UCLA head coach Chip Kelly said Wednesday before practice.

The senior running back joins running back Soso Jamabo and sophomore outside linebacker Jaelan Phillips as players ruled out due to head injuries during the past week.

Olorunfunmi missed part of training camp with an undisclosed injury this summer. When he returned to the field, he was wearing a special VICIS helmet that is designed to reduce impact forces.

When asked if he thought the frequency of concussions this year was unusual, Kelly said he didn’t think any injury, concussion or otherwise, was unusual.

“It’s a sport where I think everybody deals with it and it’s just part of what happens,” the coach said. “Sometimes they happen at one position, sometimes they happen on one side of the ball, but I don’t think there’s a pattern. But you just have to deal with it and hope that you have guys behind them that can step up.”

Olorunfunmi, who was UCLA’s leading returning rusher, played in all six games, but got just 31 carries for 85 yards. His four rushing touchdowns were tied for the team lead.

The Bruins have four scholarship running backs left, including their top three rushers. Redshirt junior Joshua Kelley leads the team with 433 yards on 73 carries. He has rushed for 100 yards in three consecutive games. Freshman Kazmeir Allen and Martell Irby have also played in every game this season, combining for 276 rushing yards. Junior Brandon Stephens hasn’t gotten a carry this year.

Moore suspended

Outside linebacker Marcus Moore has suspended indefinitely for a violation of team standards, Kelly said Wednesday. The redshirt sophomore has three tackles in four games this season.

Moore was recently moved from defensive line to outside linebacker to compensate for the diminished depth after Phillips’ injury in the second week of the season.

Quick hits

Offensive lineman Andre James (death in family) missed his second day of practice Wednesday. Jake Burton lined up at left tackle with the No. 1 offensive line in James’ place while Justin Murphy, who was still wearing a yellow, noncontact jersey, lined up at right tackle. Murphy has missed the past two games with an apparently leg injury. … Tight end Jordan Wilson and cornerback Nate Meadors were limited to individual conditioning on the sideline.
